Thus, by taking advantage of this, a system of software applications that analyses motorcycle motion and mapped out risky road sections was developed, i.e. ROCOM. The system consists of three major components, i.e. ROCOM Data Logger app, which utilizes a smart phone to collect acceleration data, ROCOM Risk Mapping app, which is a web-based application, and ROCOM Visual Tracking, which is a stand along software. ROCOM is able to detect adverse acceleration (> 2g) or vibration on the road surface similar to the High Accuracy GPS Data Logging for Vehicle Testing (VBOX). Risk mapping validation along a section of the motorcycle lane along Federal Route 2 shows that not only ROCOM have the similar risk-mapping pattern, but its route tracking capability on the map is far superior that the VBOX. The pilot and field test results showed that ROCOM works best when mounting the smartphone on the motorcycle handle bar or basket, and it can detect various road anomalies with successful detection rate of 62%, with high detection rate when passing through uneven road surfaces.","PeriodicalId":62390,"journal":{"name":"交通与运输工程:英文版","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47277008","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To save money and keep environment pollution free recycling of waste materials is the best way. Reclaimed Asphalt Pavement (RAP) is such type of waste materials, which are obtained huge amount from spoiled pavement. During this investigation an attempt is made to study the behavior of RAP materials for reuse in road construction. Aggregate Crushing Value, Aggregate Impact Value, Loss Angeles Abrasion Value and Ten percent fine value tests are also performed to determine the strength properties of coarse aggregate. Standard Marshall Mix Design procedure is followed in the design and testing of those mixes. The study reveals that untreated RAP materials are not good as a bituminous mix, but it can be acceptable with additional 1% bitumen content for use in the surface course of bituminous pavement. The investigation also indicates the possibility of adding coarse aggregate from RAP materials in the bituminous mixes with fresh aggregates, which gives satisfactory results. In our Indian subcontinent like Bangladesh, the rate of using RAP materials is very low. For that reason, the findings of the study will help in the development of sustainable road infrastructure for recycling in Indian Subcontinent.","PeriodicalId":62390,"journal":{"name":"交通与运输工程:英文版","volume":"3 1","pages":"57"},"PeriodicalIF":0.0,"publicationDate":"2018-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46003837","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This growing is increasing the necessity of innovation and new technology to respond the increment of the demand. As a respond of this demand, FAA (Federal Aviation Administration) is working with NextGen in the United States and the EUROCONTROL is implementing the Point Merge as solution in the air traffic flow management in Europe. However, the FAA alternative and EUROCONTROL alternative are not mutually exclusive since Panama, a small country in Latin America, is trying to use a combination between the vectoring approach and the Point Merge in the air traffic flow management. In addition, the AAC (Autoridad de Aereonautica Civil) and the Tocumen (Tocumen International Airport) are working in a continuous collaboration between FAA and Panama with the mutual challenge to improve the actual system. As a result, the main airline of Panama, the Compañía Panameña de Aviación (COPA Airlines), and the Autoridad de Aeronáutica Civil (AAC) constructed a simulation model to select an air traffic flow alternative that can be able to change the actual situation. In other words, COPA Airlines and AAC are pursuing the minimization of the numbers of conflicts, the number of sequence actions, the flight time, the track flight distance and the fuel burn. Furthermore, this study aims to use the final draft of this previous analysis based on a simulation methodology to conduct a Design and Analysis of Computer Experiments with the final objective to increment the statistical significance of the actual model.","PeriodicalId":62390,"journal":{"name":"交通与运输工程:英文版","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42252103","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A conventional level crossing control system is characterized by the use of two types of electronic train detectors; one detects a train approaching to a level crossing section and the other then detects the train having left the level crossing. By contrast, closed-loop level crossing control systems in which level crossing control equipment and train-borne equipment communicate with each other have been advocated and are expected to serve as an effective solution to the abovementioned issue. This paper describes the following three types of closed-loop level crossing control systems: decentralized level crossing control system, fully-centralized comprehensive level crossing control system and fully-centralized individual level crossing control system. This paper then assesses the safety of these systems in comparison to the conventional level crossing control system. For the purpose of the assessment of their safety, a new accident analysis model called STAMP (systems theoretic accident model and processes) that is suitable for software intensive systems is used to clarify the advantage of the proposed three types of level crossing control systems in terms of safety.","PeriodicalId":62390,"journal":{"name":"交通与运输工程:英文版","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67564961","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although, qualitatively and quantitatively isolated UAIDs outperform their conventional counterparts, there is no simplified procedure to consider the DLTs coordination. Hence, this research investigates the coordination of consecutive DLTs under heterogeneous traffic conditions. To achieve the optimal coordination and provide an efficient coordination control, a bandwidth maximization progression approach was used. Seeking the optimal offset for each pair of consecutive intersections to guarantee the green bandwidth waves along the coordinated corridor, a mixed-integer linear program was adopted. The optimization problem was formulated and solved based on the standard branch-and-bound technique. As a real-world study case, data of three typical intersections located in an arterial corridor in Cairo, Egypt was used. PTV-VISSIM as a microsimulation platform was employed to simulate and evaluate the different signal timing plans. However, to represent the heterogeneous traffic characteristics as close as possible to the reality, different simulation parameters were tuned and validated carefully. The results emphasized the undoubted improvement of coordinated DLTs by different operational performance indices. The total travel time, average delay, the number of stops per vehicle were obviously improved.","PeriodicalId":62390,"journal":{"name":"交通与运输工程:英文版","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42854601","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In recent years, electric vehicles have attracted considerable attention from the perspective of utilizing electricity generated from natural sources, such as solar and wind power. The propulsion method considered in the present investigation differs from the conventional off-board energy scheme in a manner such that pure stoichiometric H 2/ O 2 fuels for fuel cells are generated on-board during vehicle operation. In this method, energy conversion occurs by means of ESI-PSE (electrostatic-induction potential-superposed electrolysis). If a quasi-static process is assumed, the theoretical power requirement to produce pure stoichiometric H 2/ O 2 fuels is only 17% of the total energy required owing to a new method for supplying power to the EC (electrolytic cell). If an ESI-PSE EC is combined with a fuel cell (FC) to form an energy cycle, a HREG (hydrogen redox electric power generator) that uses solid PEMs (polymer electrolyte membranes) for the EC as well as the FC can be realized. According to calculations based on data from the operational conditions of commercially available ECs and FCs, more than 70% of the power delivered from the FC can be extracted for driving a motor constantly while a car is in motion. Because of energy self-sustainability on the HREG side, the power control system should not have any power loss. This propulsion system will realize tough vehicles that can continue running at a top speed at long unlimited cruising range.","PeriodicalId":62390,"journal":{"name":"交通与运输工程:英文版","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43131432","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
